/>

## Controlled

Use the `value` and `onChange` props to control the value of the slider.

<ComponentPreview
  name="color-area/demos/controlled"
  preview={`const [value, setValue] = React.useState(parseColor("hsl(0, 100%, 50%)"))
return <ColorArea value={value} onChange={setValue} xChannel="saturation" yChannel="lightness" />`}
/>

## Channels

`xChannel` and `yChannel` props may be provided to specify which color channels the color area should display

<ComponentPreview
  name="color-area/demos/channels"
  preview={`<ColorArea xChannel="red" yChannel="blue" />`}
/>

## Options

### Disabled
